20140279292 | Dynamic Inventory Tracking and Transfer System - A dynamic inventory tracking and transfer system is provided that, when in operation, keeps track of inventory by tracking vehicle positions and inventory transfers. A transceiver on a vehicle detects and transmits a signal to the tracking system whenever a vehicle latches onto inventory and/or releases (i.e., unlatches) inventory. Whenever latch and unlatch signals are detected close in proximity to one another, the system concludes an inventory transfer has been made between the two vehicles. The inventory monitoring takes place in real time, thereby allowing inventory to be tracked from the time it is removed from a ship/train to the time it leaves a sea port, rail terminal or industrial yard. | 09-18-2014 |
20140277688 | Light Positioning System and Method of Using the Same - A light positioning system for use in transferring a container to a buffer is disclosed.
